In 1982, an experimental solar power plant was built near Manzanares in the province of Ciudad Real, Spain. The centerpiece of this project was a 195-meter-tall steel chimney, designed by the German engineering firm Schlaich Bergermann & Partners under the leadership of engineer Jörg Schlaich. Funded by the German Ministry of Research and Technology, the plant aimed to explore a novel method of generating electricity using solar energy. Although it operated for seven years, exceeding its initial three-year plan, the structure collapsed in 1989 due to rust in the supporting guy wires, not a flaw in the solar technology itself. The plant relied on a simple yet effective principle: hot air rises. The system featured a central chimney, 10 meters in diameter, surrounded by a circular solar collector 244 meters wide. This collector was covered with 6,000 square meters of glazing positioned 2 meters above the ground, allowing sunlight to heat the air beneath. As the air warmed, it rose through the chimney, spinning a turbine at the base to generate electricity. The expected output was 50 kilowatts, enough to power a small number of homes. The structure was intentionally built with inexpensive materials, such as 1.25 mm thick iron sheeting, to keep costs low, as the main goal was to test the concept rather than create a long-lasting structure. The solar collector also acted as a testing ground for various materials, including different types of glazing and plastics, some of which proved too fragile. In addition, part of the facility was used as a real greenhouse, showing how the site could serve multiple purposes in an experimental setting. Despite its collapse, the plant provided valuable data on how solar chimneys function in real-world conditions. Researchers gained insights into the thermal and aerodynamic behavior of such structures, which helped inform future designs. The engineering firm Schlaich Bergermann & Partners continued developing solar tower technology in the 1990s and later partnered with the Australian company EnviroMission for a large-scale project in western Australia. However, no full-scale solar chimney has been built since the Manzanares tower collapsed. While the concept of solar chimneys remains attractive due to its mechanical simplicity and ability to operate on cloudy days, the cost of producing electricity is still higher than conventional power sources or traditional solar panels. Forty years after its collapse, the Manzanares chimney remains the only real-world example of a large-scale system that uses hot air alone to drive a turbine. Its legacy continues to inspire research into alternative energy solutions.
